Thank you!
We have decided to go with VMDUMP rather than disk-based dumps. I will try
making vmhalt=VMDUMP. The "Dump Tools" book seems to be for the October
2005 stream, but I read it anyway. It did help.
Thanks again!

Toto, I have a feeling we're not in the mainframe world any more.

You're right that one dump disk per server does not scale, and picking
one from a pool is not trivial (well, a pool of 1 could do). But you
would be better off with VMDUMP instead.
If the kernel crashes the CP READ wil make evidence disappear before
you're there to take the dump. My understanding is that the kernel
does a halt in case of bad damage, in that case vmhalt="VMDUMP 0:ALL"
would do the trick. Have a look at the "Using the dump tools" book
which describes the process to read in the dump in Linux (in the Linux
that caused the dump, or at least one with exactly the same level of
kernel).
